However, there is one thing in the current behavior that I would even
consider a bug: if one starts VDR with

 vdr -v /mydir

it uses /mydir as the video directory, but still uses /video for the
configuration files. I believe that as long as there is no explicit
-c option given, the config directory should follow what's given in
the -v option. So I wouldn't mind if this was fixed along with implementing
the FHS stuff ;-) (or in a separate step).
